“Well, it’s outrageous. I mean, it’s an outrageous statement, and she will be called on it,” Ms. Fiorina, the former Hewlett-Packard CEO, said Friday on Fox News.

Campaigning in Ohio Thursday, Mrs. Clinton, the 2016 Democratic presidential front-runner, said: “Extreme views about women, we expect that from some of the terrorist groups. We expect that from people who don’t want to live in the modern world. But it’s a little hard to take [coming] from Republicans who want to be the president of the United States.”

“And what it tells us is that Hillary Clinton has no qualms about continuing to try and wage this supposed ‘war on women’ card as she runs for president,” she continued. “We ought to expect this. Democrats are continually describing Republicans as extreme when the truth is, it is Democrats who are extreme.

“They are extreme as she continues to defend Planned Parenthood. Planned Parenthood can no longer be defended, and yet Hillary Clinton is out there defending them,” Ms. Fiorina said. “It’s unclear that she’s ever had the courage to watch these videotapes, to actually see what Planned Parenthood is doing.

“So Hillary Clinton and her party are the extremists here on a whole series of issues, and her comparing any Republican to a terrorist is simply over the line,” Ms. Fiorina said.

Ms. Fiorina said that while the landscape has changed on the Democrats’ “war on women” line, Republicans still need a nominee who is “unafraid” to push back.

“What I intend to keep on doing, and I have been doing it from the very beginning, is calling her out, and any other Democrat out, on the extreme positions that they hold,” she said. “The policies that Hillary Clinton and other Democrats will pursue are bad for women, and we need to keep making that point over and over again.”

She said women have higher positions and are better paid on her campaign than on Mrs. Clinton’s campaign.

“So not only is she extreme, but she’s hypocritical as well,” she said.
